2546	Wrong OpenCL driver used on machine with Nvidia and Intel GPUs	Tristan Croll	Tristan Croll	"Bug report from Joel Mackay in Sydney. On his Windows machine attempting to start a simulation in ISOLDE crashes ChimeraX. I'll attach the crash log he sent me, but it boils down to the system providing the Intel OpenCL driver (igdrclneo64.dll) ahead of the Nvidia one. There are many discussions of the same problem online - see https://www.addictivetips.com/windows-tips/force-app-to-use-dedicated-gpu-windows/ and https://www.daz3d.com/forums/discussion/243216/getting-a-fatal-error-on-launch-solved for example. Apparently one solution that amazingly seems to work without breaking anything is to just delete that DLL, but that's hardly a general solution. It seems it's possible for programs (especially games) to register themselves as requiring the high-powered GPU if available... might be an idea for ChimeraX to do so?

Otherwise, I can see if I can figure out how to make OpenMM specifically be more picky about which driver it uses."	defect	closed	major		Structure Editing		not a bug		Tom Goddard				Windows 10	ChimeraX
